Figure 4
Analysis of anatomical parameters from the data. (a) 3D rendering of the sample structure from scan Bone3 (Frelon camera, 29.6 keV X-ray energy) after segmentation. The scaffold material is shown in a transparent purple hue, the bone in orange and porosities in cyan. Size of the visualized volume is 22 µm × 20 µm × 22 µm. (b) Example gray value slice through this cropped dataset. (c) Segmentation corresponding to image (b), with the same coloring as in (a). White arrows highlight isolated porosities considered for image quality analysis, i.e. roughly spherical objects of the porosity phase that are not in contact with the bone.
